滲流沖刷 的英文怎麼說
中文拼音 [shènliúchōngshuā]
滲流沖刷
英文
seepage erosion-
Thus, the piping - induced failure of two - layer foundation was verified as that : mass flow firstly appears in the upper weakly permeable layer, and then underground erosion and scouring gradually occur from downstream to upstream between the serviously and weakly permeable layers
從而驗證了二元結構堤基的滲透破壞模式為:首先在上層弱透水層中發生流土,然後在強、弱透水層之間發生自下游向上游的逐步潛蝕沖刷。This paper presents a method of probability analysis in order to develop the general design and analysis methods for problems of the embankment stability under random storm wave actions as well as with random properties of the embankment medium. the major purpose of this study is carry out modellings of ( 1 ) probability analysis for the problem of seepage stability of levee projects ; ( 2 ) probability analysis for the problem of erosion due to washout sediments from the embankment ; ( 3 ) numerical analysis for coastal evolution due to beach erosion under energy actions of storm wave
本文根據598084號年浙江省自然科學基金項目和g59901號國家教育部回國留學人員科研啟動基金項目的部分研究目標和研究內容的要求應用概率分析方法研究了在隨機風浪荷載作用下和築堤材料隨機性影響下防護堤壩抗滲流、抗沖刷穩定性的分析計算模型;用數值分析方法研究了在浪潮能量作用下岸灘侵蝕造成海岸演變問題的數學分析模型。For example, after the collapse of ditong dam in idaho, may 5, 1976, it was found that it was not impervious very well, the impervious curtain was built poorly. when the seepage went through the impervious curtain, the exit water from the pervious material of the downstream or the right side of dam through the foundation or certain line between the foundation and the dam caused contact scour and piping
如美國愛得華州提堂壩於1976年5月5日潰決,事後調查分析,因壩基透水性大,防滲帷幕施工質量差,滲流穿透帷幕,經地基或地基與壩的接觸面從壩體下游側透水料區逸出或從右壩肩繞滲經下游壩體逸出,出逸的水流引起了接觸沖刷和管涌,導致潰壩。The characteristic of top soil will changed by splash erosion and surface erosion, accordingly to alert the route of runoff and seepage and work to unconsistenty of soil erosion
棄土場坡面地表土壤特性隨著降雨擊濺和徑流沖刷的作用而發生變化,從而影響區域內徑流和滲流途經,造成坡面產流的不一致性。By means of prototype observation, analysis with materials and theories, and laboratory test, the author deeply analyzed the causes and procedure of canal cross section erosion, and obtained eight causes which resulted the canal deform including flow, seepage, runoff, collapse of bank, dry effect, human activity, wave flush, frozen, and then stressed to discuss the frozen process
本文通過原型觀測、資料分析、理論分析、室內試驗對北引渠道變形的成因和發生機理進行了較為深入的分析研究,給出了造成北引渠道變形的八大原因:流水引起的變形、滲透引起的沖刷、地表徑流引起的沖刷、滑坡變形、乾燥作用、人類和動物活動的影響、風浪引起的沖刷、凍融侵蝕,並著重闡述了凍融侵蝕的機理。分享友人
